IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 155,258, dated September 22, 1874 application filed August 15, 1874.

To all whom t may concern:

Be it known that I, ABrsHA B. RENIEE, of Binghams Mills, in the county of Tioga and State of New York, have invented a new and Improved later-Wheel, of which the following is a specification:

My invention relates to turbine wheels, in which the water is admitted through a horizontal annular stationary chute-rim to a horizontal annular bucket-rim of the wheel; and it consists of the buckets arranged radially to the axis of the wheel between two circular plates which converge from the top downward a third, or a little more, of the Width, and then continue parallel to each other to the bottom, either with or without converging side plates to the chutes; and the buckets incline forward about one-third of their length, and backward the rest of their length in straight lines, making a simple and efficient wheel.

Figure l is a sectional elevation of my improved wheel. Fig. 2 is a detail section, taken on the line x a' of Fig. 3, and Fig. 3 is a plan or top view, partly in section, representing the buckets and chutes.

Similar letters of reference indicate corresponding parts.

A is the shaft of the wheel; B, the arms 5 C, the inner bucket rim or plate; D, the buckets; and E, the outer bucket rim or plate. These bucket-rims are made to converge from the top downward about one-third or a little more, and parallel to each other the rest of the way, and above the buckets the plates or rims G I of the chutes also converge a little, the object being to contract the spaces in about the same measure that a column of water contracts in passing through an orifice under pressure, to maintain solid columns in the passages, entirely filling them instead of the broken columns only partly filling them, incident to passages of the same, or nearly the same size, throughout the length.

The sides of the chute-rim need not necessarily be convergent, but they are better so.

a represents the forWard-inclining portions, and b the backward-inclining portions, of the buckets, which are otherwise radial to the axis of the wheel. J is the flan ge ofthe chutecase, by which the latter is supported on the bottom of the Hume. F and L constitute the top of the chute-case, and K is the gate;

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The bucket plates or rims E C, partly converging and partly parallel, as described, in combination with the forward and backward incliuing radial buckets D, with or without converging chute-rims G I, substantially as specified.
